**12 tools: 1 change things and 11 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

## Findings

- **warn** Annotations that disagree with the tool in `open_snapshot` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "open_snapshot" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "open_snapshot" says "open": a word for a change.
```


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `open_snapshot`

- The name "open_snapshot" says "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Store supplied source files ephemerally and return an opaque snapshot handle for reuse.
```

## Only reads (11)

Looks things up and changes nothing. Claude Code: allow.

### `analyze_impact`

- The name "analyze_impact" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```

### `find_references`

- The name "find_references" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return semantic static references to one exact compiler symbol.
```

### `find_symbol`

- The name "find_symbol" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve a symbol name to deterministic ranked compiler symbol candidates; safely reports ambiguity.
```

### `get_capabilities`
